Abstract: A single layer structure of micron or nano fibers, and a multi-layer structure of micron and nano fibers. The single layer structure of micron fibers includes a web of micron fibers and an impregnating resin, and has a pore size of 1 nm-500 nm. The web of micron fibers is formed by plural interweaved micron fibers (D?1 ?m). The single layer structure of nano fibers includes a web of nano fibers formed by plural interweaved nano fibers (D<1 ?m). The multi-layer structure of micron and nano fibers includes a web of interweaved micron fibers, a web of nano fibers formed by plural nano fibers interweaved on the web of micron fibers, a mixture layer formed by parts of the interweaved nano and micron fibers, and a resin at least impregnating the mixture layer and parts of the micron fibers of the web of micron fibers.
